chore(deps): bump hono from 4.12.4 to 4.12.16

[dependabot]

Bumps hono from 4.12.4 to 4.12.16.

Release notes

Sourced from hono's releases.

v4.12.16

Security fixes

This release includes fixes for the following security issues:

Unvalidated JSX Tag Names in hono/jsx May Allow HTML Injection

Affects: hono/jsx. Fixes missing validation of JSX tag names when using jsx() or createElement(), which could allow HTML injection if untrusted input is used as the tag name. GHSA-69xw-7hcm-h432

bodyLimit() can be bypassed for chunked / unknown-length requests

Affects: Body Limit Middleware. Fixes late enforcement for request bodies without a reliable Content-Length (e.g. chunked requests), where oversized requests could reach handlers and return successful responses before being rejected. GHSA-9vqf-7f2p-gf9v

v4.12.15

What's Changed

• fix(jwt): support single-line PEM keys by @​hiendv in honojs/hono#4889

New Contributors

• @​hiendv made their first contribution in honojs/hono#4889

Full Changelog: honojs/hono@v4.12.14...v4.12.15

v4.12.14

Security fixes

This release includes fixes for the following security issues:

Improper handling of JSX attribute names in hono/jsx SSR

Affects: hono/jsx. Fixes missing validation of JSX attribute names during server-side rendering, which could allow malformed attribute keys to corrupt the generated HTML output and inject unintended attributes or elements. GHSA-458j-xx4x-4375

Other changes

• fix(aws-lambda): handle invalid header names in request processing (#4883) fa2c74fe

v4.12.13

What's Changed

• fix(types): infer response type from last handler in app.on 9-/10-handler overloads by @​T4ko0522 in honojs/hono#4865
• feat(trailing-slash): add skip option by @​yusukebe in honojs/hono#4862
• feat(cache): add onCacheNotAvailable option by @​yusukebe in honojs/hono#4876

Greptile Summary

This PR bumps hono from 4.12.4 to 4.12.16 across two package manifests and regenerates the lockfile. The upgrade resolves three security advisories (HTML injection via unvalidated JSX tag names GHSA-69xw-7hcm-h432, bodyLimit() bypass for chunked requests GHSA-9vqf-7f2p-gf9v, and JSX attribute name injection GHSA-458j-xx4x-4375).

• hono bump: Both apps/examples/hono-example/package.json and packages/hono/package.json move from 4.12.4 to 4.12.16; the lockfile is updated accordingly with the new resolution integrity hash.
• Lockfile collateral changes: The lockfile regeneration also surfaces newly deprecated entries for @ungap/structured-clone@1.3.0 (CWE-502), uuid@8.3.2, and glob@10.4.5, and bumps several indirect dependencies (graphql, tough-cookie, tldts, type-fest, turbo).

Confidence Score: 5/5

Safe to merge — the change is a pure security patch bump with no API-breaking changes within the 4.12.x line.

The hono upgrade is patch-range only (4.12.4 → 4.12.16) and resolves three disclosed security advisories. The lockfile collateral changes (graphql, tough-cookie, tldts, turbo) are all minor/patch bumps without breaking changes. The @ungap/structured-clone CWE-502 notice is a pre-existing transitive dependency issue surfaced by the lockfile regeneration, not a regression introduced here.

No files require special attention; the lockfile's newly surfaced @ungap/structured-clone@1.3.0 deprecation is worth a follow-up in a separate PR.

Security Review

• GHSA-69xw-7hcm-h432 (hono/jsx): Missing validation of JSX tag names in jsx()/createElement() allowed HTML injection — fixed in this update.
• GHSA-9vqf-7f2p-gf9v (bodyLimit middleware): Chunked / unknown-length requests could bypass the body size limit and reach handlers — fixed in this update.
• GHSA-458j-xx4x-4375 (hono/jsx SSR): Missing validation of JSX attribute names during SSR could corrupt generated HTML and inject attributes/elements — fixed in this update.
• CWE-502 (@ungap/structured-clone@1.3.0): Deserialization vulnerability surfaced as a deprecated notice in the regenerated lockfile; not introduced by this PR but warrants a follow-up upgrade to ≥1.3.1.

Important Files Changed

### Issue 1 of 1
pnpm-lock.yaml:3152
**Deprecated transitive dependency with deserialization vulnerability**

The lockfile regeneration surfaces `@ungap/structured-clone@1.3.0` as deprecated with a `Potential CWE-502` notice. CWE-502 (Deserialization of Untrusted Data) can allow remote code execution if attacker-controlled data passes through the `structuredClone` polyfill. While this is a transitive dependency and not directly introduced by this PR, it is now explicitly flagged. A follow-up PR should identify which package pulls it in and upgrade to `@ungap/structured-clone@1.3.1` or higher to clear the advisory.
